Casement Windows
Sustainable style with form and function
Casement windows are one of the most versatile and enduring window styles for British homes. At Spittlywood, we design and build bespoke timber casement windows that combine traditional aesthetics with modern performance offering excellent ventilation, high energy efficiency and timeless character.
Hinged at the side and opening outwards, they provide wide, unobstructed views while promoting natural airflow throughout your home.
Every casement window we create is custom‑built in our Kent workshop using a balance of precise CNC engineering and skilled craftsmanship. The result is a window that performs exceptionally well in all seasons: tight seals for insulation during cold months and smooth, full opening capability for warm weather ventilation.
Bespoke Casement Windows
Our casement windows are designed not just to look beautiful, but to deliver long‑lasting performance. Whether you’re upgrading existing windows, replacing damaged frames, or renovating a period property, our experienced joiners ensure every detail is correct from the timber selection and mouldings to the glazing and finish.
We also offer engineered Lingum timber casement windows, which provide outstanding structural stability, aesthetic flexibility and sustainable performance for both traditional and contemporary properties.
Our team manages the process from start to finish, ensuring a smooth, stress‑free experience from design consultation through to installation.
